To all whom e'tmay concern:

Be it known that we, ALFRED STELL and JOHN STELL, subjects of the King of Great Britain, and'residents, respectively, of Greenhill, Steeton, near Keighley, in the county of York, England, and 30 Devonshire street,

Keighley aforesaid, have inventedfa certain,

new and useful Improvement in Dot'fing Apparatus for Spinning and like Machines, of which the following description, together with the accompanying sheets of drawings, is a specification.

Our invention relates to improvements in dofiing apparatus for spinning, twisting, doubling and like machines used inthe production of yarns or threads of fibrous substances, particularly of the typeknown as flier spinning machines, and wherein the spindles are supported in bearings at their upper ends. Our present inventionconsists in the application of improved devices to do'fiing apparatus of this description for the purpose of holding uponand releasing the full bobbins from their spindles, the same device beingalso employed for supporting and moving the empty bobbins and for guiding or moving the yarns or threads to the desired sides of the spindles at the time and in the manner hereinafter described. These devices are carried by the parts which operate or movethe railsupporting the spindles, by which means they are at all times simultanously moved, although portions thereof are separately movable relativelyto the spindles in the manner and forthe purposes hereinafter described.

In the accompanying sheets of drawings Figure 1 is a sectional end elevation of a suliicient portion of a machine for spinning, flax, hemp, jute, or the like, to show the application of our invention thereto, the spindles being shown in thespinning position.

Fig. 2 is a similar viewto Fig. 1, but illustrates the-spindles as though cantedormoved at an angle to the vertical plane.

Fig. 3 is a front elevation of a portion of said spinning machine the spindles being shown in dotted lines in order that our improved parts may be more clearly seen.

Our improvements are equally applicable to machines for spinning or treatlngwoolen ior' worsted yarns, or flax, jute or other similar yarns or threads.

In the accompanylngsheets of drawings represents the spindles upon which the fliers 1 are mounted, these being supported at their upper ends by the rail 2, and are driven by whirls 8. The plate 2 is movable upon its fulcrum l'which is supported by brackets 5 from therail 6 which extends across-the machine. The spindles A are steadied at their lower ends by bearings 7 in the spindle. rail 8. Racks 9 and pinions '10 operated from the shaft 11 raise and lower said rail 8, the shaft 11 being oscillated by an appropriate handle of well known type mounted at the end of the machine, the oscillations of the rail 2 being also effected by anotherhanolle mounted at the end of the machine. The lifterplate 12 is traversed in any well known manner as by the rod 13, chain lhchain pulleys 15, and a shaft 16, these beingautomatically rotated from the building motion: of the machinein order that the bobbins BInay be reciprocated atthe desired .rate of speed between the lower ends of the fliers 1 to regulate the winding of theyarns on thebobbin's B in their proper positions thereto. Means are also employed for rotating the shaft 16by hand for, the purpose of manually raising and lowering the lifter plate 12 as and when ever desired. The crossbar 17 is employed as a guide for the racks 9 and other parts,

as will be readily understood. lln the case of machines for spinning flax and the like, tension is applied to the'bobbinsB by the bands 51 and weights52 the former resting against the surfaces ofgr'ooves formed insaid bobbins, and means of any desired constructlon are employed for snnultaneously applying and removing said tension bands.-

Incarrying our invention into effect we mount quadrants 18 upon the cross rail'Q and these quadrants 18 gear with other quadrants 19 fixed at'desired intervals upon the shaft 20' any suitable means, such as the well known quadrant lever (not shown) being employed to hold said shaft, so that it definitely. occupies two positions, one when the spindles are in their vertical positions, 7 as shown'by Fig. 1, and the other when they are in their inclined positions as shown by LFigQ. The operative maythen know-that by said 'leverresting within one notch or the other the spindles are in. one oftheir two correct ,positions,jnamely, the yertical .r si m'e d hat in rh e r ar ve 20 the spindles A.

' to liberate the-full bobbins and have empty ones substituted therefor.

Mounted in brackets 21 on the quadrants 18, is a rod 22 having fixed upon it the usual 5 series of devices'23 for steadying the spindles A, this shaft 22- being oscill'ated by a handle arranged at theend of the machine .for the purpose "of m oving said steadying arms into or out of contact withithe spindles A the two positions being indicated in full.

The shaft 30 is provided 30 with series-of plates3l mounted thereon ielees t en opp i r ex ly pe site-to the spindlesA, and; these plates have one, two or more projecting pins 32, which are} forfthe purpose of entering the yarns on the fullbobbins whensame are'fin their positions upon the spindles 'A either when sai p n l s a e cal at "enim g t the vertical plant-3.; 'lfhos'cillationjof the {shaft 30 draws such pins "away. from the v 40 bo 'bbiiis whereby' they may be released to fall upon {their pegsgin mannerhereinafter described,while-by advancing the racks 3O and "lowering the'racks '26' into an; appropriate position gsaid pi-ns 32 {maybe em- 4 "?'ployed ;to lay. hold of the threadsextending fromthe fullbobbins to the-fliers and move themjto the "requisite sides ofthe spindles and, t rJQW ns ei r ks s is l ff -ther and again oscillating the shaft 30 'the pins-32 may be passed beneath the flanges iefst F m-p 3 bo i 33, whe bvmising the racks26said empty bobbins 33 are also raised on their spindlesand heldthere until Y the 'lattergare returned to theirvertical posi- 5 ations after dofiing operations have been performed, 1 the pins being withdrawn by withdrawing the racks 26 within their. bearing -27- We preferably employ two series: of pegs 343 35, whieh maybeinrou-nted upon one rail -;or upon two rails 36, 37,:as s o time a 4013 Supreme by apprQprim-ba suitablemeans (not shown) being employed to limit movement of said shaft, so that the series of pegs 34, 35, -1nay be moved from the position they occupy in position they occupy in F ig. 2, the former being that'whe'rein the pegs 3&- receive the series of full bobbins B, and in Fig. 2 that Fig. 1, to the V inwhich the full bobbins have been moved away and the spindles A are in position for receiving the series of empty bobbins 33 as they are raised upon said spindles from their pegs 35. In both cases one of the series of pegs is in alinement or atthe same inclination as the series of spindles A. The

yarn is' severed in any suitable manner, a 86 well known form of device 42, being conv'entionall illustrated.

The 'doi'ng operations as performed by our improved "parts and the others of well known form as herein described, are as fol- 5 lows'zfAs'suinlng that the bobbins B have received the necessary quantity of yarn and 'dles"A' is then-lowered as is also the lifter plate 12,350 as to both be clear of the lower I s ends of'thesp1ndles,'after which, the rail 2 is canted, or moved into 'the position indi- --cated by Fig. 2, by therotation of the'shaft 20,-thi1s carrying with i't'th'e parts support-ed by 'thequafdrants 18: hence-the full bobbins Bwill still bes'u'pported upon-their spindles by the pins 32. The shaft 28 is nowi'ol a'ted in the opposite direction so as to withdraw sai'd'pins32 from the yarns onthe bobbins B, these latter then being allowed to fall v upon the pegs'3 which'will'be in the position at this time as indicated 'by Fig; 1.

The racks 38 are then moved by the shaft 40 so as to carry the two series of pegs 31,

35,:in't'othe positions indicated by Fig.2,

wherein the pegs 35 are in alinement with said spindles A, and the pegs 3st moved away therefrom, The racks 26 are then lowered ;to a suitable position where by advancing the racks 30 and rotating the shaft 30 the pins ;32 may lay hold of the threads and fmovethem to' the proper sides of said spindle's A, after which, said racks are slightly lowered and said [pins 32 passed beneath the flanges of the bobbins 33, so that byraising theraeksz26 by'the rotations of the shaft 2 P said enipty bobbins are raised to an appropri'ate position'over the spindles A when the ,rail 2 is. again oscillated .to b ing ;the

spindles into'the'positions indicated by Fig.

1.. ,The lifter plate 12 and spindle rail .8 are then raised to their normal positions and the thread severed by any of the .Well known forms of thread cutting devices, conventi'onally illustrated at 42.- .The steadying.

pinsor arms 23 and pins 32 arereturned to their normal positionsland the bobbins 33 allowed to fall .on to thelifter plate 12 in contact with which they are subjected to a certain amount of drag and to the action ,ofthe device for imparting a drag to their side parts as hereinbefore described. A few turns are then given to the spindles after Which the threads are severed in manner Well known. Thespinning operations may then be recommenced. From the foregoing description it 'Will be seen that the performing ofthe dofling oper- .ations is'considerably. facilitated by having supported from the parts which carry the spindles the means for holding and releas- 7 ing the full bobbins, for supporting and moving the empty bobbins, and for moving or guiding the threads;
